This study will involve a single study session (lasting two hours) in the controlled setting of a research laboratory. This study will evaluate whether older adults who have had unintentional falls are willing to enroll in this kind of study, use the device briefly, and undergo research assessments. The study will also test whether using the virtual reality device leads to detectable changes in gait, balance, and mobility confidence. This study will lay the groundwork for more comprehensive studies in the future that will assess the clinical impact of using the device.
